Gomphandra, traditionally in the Icacinaceae, is resolved as one of the five genera contained in a strongly supported clade based on ndhF, rbcL, atpB, and 18S rDNA genes, which led to the establishment of a new family, Stemonuraceae (Kårehed, Amer. J. Bot. 88: 2259-2274. 2001).

About 33 species: tropical Asia to NE Australia; three species in China.
